HCF takes the LOW powers, LCM the HIGH
Line the two numbers up by prime. HCF keeps the smaller power of each shared prime; LCM keeps the larger of every prime.
12 = 2^2 × 3^1
18 = 2^1 × 3^2
HCF = 6
lowest power of each shared prime
LCM = 36
highest power of every prime
💡 HCF × LCM = 6 × 36 = 216 = 12 × 18 = 216. Always true — for two numbers.
